Au contraire, this is really easy to do, provided you can afford
to run an additional mail server, which i'll call
fascistfiltering.columbia.edu just for the example. Then simply put this
entry in your mailertable:
aol.com smtp:fascistfiltering.columbia.edu
Make sure fascistfiltering allows relaying from your other mail server.
You can even run mimedefang on the fascistfiltering machine, of course.
You might want to block incoming SMTP connections to fascistfiltering
except for connections from the mail server.
